The or operator allows us to select all the statements in the database as long as one of two conditions
is met if we change the last name.
In this example back to King
we know that the resulting output will be zero records
but take a look at what happens if we change the operator from and to or
now we have two records output it.
The reason is we have one record where the first name is Ted but we also have another record where the
last name is King
since only one out of two conditions have to be met we get an output of both records.
